Be it known that I, WAL'rinL D.y Gr-ILES, a citizen of the .United States, residing at Leesville, in the parish of Vernon and State of Louisiana, have invented certain new and -useful Improvements in a Saddle, of which the following is a specification.

This invention appertains to novel means for connecting the polish or pump rod of'a pump structure and has for itsprimary object to provide vnovel means for supporting the polish or pump rod bysaid coupling, said means including a ball bearing support whereby rotary movement of the polish or pump rod is permitted, thereby effectively means supported by said cap or saddle forv connecting the saine with the polish rod support.

A still further object of theinventionis I to provide an Vimproved device of this character, which will be durable and efficient in use, one that will be simple v andeasy to manufacture and one which can beplaced upon the market at a smallcost.

lVith these and'other objects in view, the inventiony consists in the novel construction, arrangement and formation of parts, as will be hereinafter more specifically described,- claimed and illustrated in the accompanying drawings, in which drawings:

Figure 4 is a detail perspective view of one of the antifriction Babbitt metal plugs carried by the terminals ofthe cap or saddle.

Figure 5 is a central vertical transverse section throughthe improved cap or saddle.V

Figure 6 is a top plan view of the cross bar, which forms'an important part of the invention, and- 1 Figure 7 is a vertical longitudinal section through the cross bar showing the ball bearing means for connecting the polish pump rod with the crossbaia Referring to the drawings in detail, wherein similar reference' characters designate corresponding parts throughout the several vie-ws, the letter Av generally -indicates the improved device for connecting a polish or Va wear 1S of thel swing-i 645 and embodies anlfupper. saddleorvcap i 15, a lower cross bar 25meansjf'35 for con-y necting the cross'bar 25 with the saddle or cap 15 and the novel b all bearing means 40 for rotatably connectingthe'polishyor pump rod B with the crossbar 25. `The improved cap or4 saddle., includes-a longitudinally extending castl body 16 which is adapted to extend transversely of the walking beam C and the lower edgeof ythis bodyis of a substantial cylindrical shape as indicated at 17 to form a rocker, which is -adapted to rest upon the wea-r plate 11. rlhe upper edgeof the body 16 is providedwitlh an arcuate guide 18 which is of a substantially U-,shape in cross; section, for Aslidably receiving the means 35 for connecting the cap Vor saddle 15 with thel crossrod 25. The terminals of the body 16 adjacent Ito its lower edge is provided with vkeyes`19v which receive tapered antifriction plugs 20.which are preferably formed of Babbitt metal or the like. 1: i

The cross rod 25 is provided with a central hub 26 and outwardly extendingdiametrically disposed arms 27. Thisfcross rod 25`is also preferablyY formed from a single casting and the arms 27 adjacent to 'the terminals thereof are enlargedto provide eyes ,28 andthe extreme terminalsvof the arms are grooved as at 29 to provide guides for a purpose, which will be hereinafter more fully described. `The central hub 26 is providedv with an axial bore 30 andthe bore adjacent to its upper end isenlarged as at 31 forming` a vshoulder 32, which defines a racevvay,v as 'will be hereinafter-"more fully described.

The means for connecting the crpss rod 25 with the saddle or cap 15 embodies a flexible cable or the like 36 Which has its' intermediate portion fitted Within the guide 1S formed on the body portion 1G-fof said cap or saddle 15. The ends of the flexible cable 36 arev then threaded throughthe antithreaded throughthev eyesQS` 'formed inthe l cross rod 25V and up through 'thef guilde grooves 29,. The Vterminalsv olijthef cableaie' 'chen clamped tothe portions othetiabledirectly above the eyes 28, as at 37.

The novel -means40 for `connectingfthe polish" or pump rod Bwith the icrosshead includes a sleeve'41 'which isfadapted to extendthrough'the axial WayBOin the'li'ub-l 26 of the cross bar lor rod k25. 1rllhisl sleeve 41 is provided with an enlarged ai'inular` enlarged portion-32 ott-he bore 30. Suitable ball bearings 43 are interposed between the head 42 and the shoulder 32, formed by'l the enlarged portion22 of' the'borel"a.nlil"the inner face of the enlarged headBQl 'eanbe suitablyrformed to provide a''racevvay Jor the said ball bearing.

LA two-part clamp ,44eng`ages the polish rod vand s'irmly' securedf thereto by Vsuitable Y boltsl'45. lThis cla'mpj44`rests uponfthe upper surface 'of the enlarged'head42 of the sleeve 41. lThe lower fendo' the sleeve'-A has connected therewith' by means of a set screw 46 or thelike acollar47`ivhichisadapted to Vel'igage thelovver surface 'ofthe hublQG 'of I the variousv sections of' the VArod; I"in" fvi'ewvpb the cross bar orirod'Q.

1t thus p can be seen "t that the*cro`ss bar *or Y rod" '25 lis svv'ingablyisiipported' Aby the=` the fact, v'if"""`any 'section;"offthefiiod has a tendency to turn, the" ivhle 'r'od'xvillfbeiper;

mitted to freely turn therewith. IFurt'herthe provision of the ball bearing relieves allcjar incident to the pumping operation.Y
